Description

Technical Field

[0001] This utility model relates to the technical field of material conveying, specifically a material flattening device for a transport line. Background Technology

[0002] Irradiation technology is a technique that uses the interaction of rays (such as electrons, gamma rays, etc.) with matter to activate atoms and molecules through ionization and excitation, thereby causing physical, chemical or biological changes in the matter. Its applications are very wide, including but not limited to food preservation, sterilization of medical and health products, processing of polymer materials, environmental protection, and industrial wastewater treatment.

[0003] During the irradiation process, the material to be irradiated is first placed on a tray, and then the tray is placed on a transport line to be transported to the irradiation chamber, so that the material is continuously irradiated, allowing the rays to penetrate the packaging bag and destroy the DNA of microorganisms, thereby achieving the purpose of sterilization / preservation.

[0004] To eliminate thickness differences, avoid "irradiation dead zones," and ensure uniform irradiation penetration and consistent dosage, the materials on the transport line need to be flattened before entering the irradiation chamber. However, the current method of flattening materials is generally done manually, which is inefficient and the flattening effect is generally poor, thus affecting the subsequent irradiation effect to some extent. Utility Model Content

[0005] The purpose of this invention is to provide a material flattening device for a transport line, which solves the problems of low efficiency and poor effect in flattening materials and improves the effect of subsequent irradiation of materials.

[0006] To achieve the above objectives, the utility model employs the following technical solution: A material flattening device for a conveyor line includes a base frame disposed on both sides of the conveyor line, a movable frame slidably connected to the base frame, a screw threadedly connected to the movable frame and rotatably connected to the base frame, a slider slidably connected to the movable frame, a pressure roller disposed between two sliders, a limit block slidably connected to the slider, a limit groove disposed on the movable frame, a plane contacting the limit groove on one side of the limit block, an inclined surface contacting the movable frame on the other side of the limit block, and a spring disposed between the limit block and the slider.

[0007] Furthermore, the end of the screw is provided with a driven wheel, the driven wheel is provided with several radial grooves, a drive wheel is rotatably connected to the base frame, and both the upper and lower sides of the drive wheel are provided with levers that contact the radial grooves.

[0008] Furthermore, an arc-shaped groove is provided between the two radial grooves, and arc-shaped blocks that contact the arc-shaped groove are provided on both the left and right sides of the drive wheel.

[0009] Furthermore, a handle is provided on one side of the drive wheel.

[0010] Furthermore, the pressure rollers are in multiple sets.

[0011] Furthermore, the base frame is provided with several vertical slots, and the movable frame is provided with guide blocks that are slidably connected to the vertical slots. After passing through the vertical slots, the guide blocks are provided with rollers that are in rolling contact with the base frame.

[0012] Furthermore, a first bearing is provided between the slider and the pressure roller.

[0013] Furthermore, a second bearing is provided between the screw and the movable frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. When installing the pressure roller, fix both ends of the pressure roller to the slider. Then, with the inclined side facing the movable frame, slide the slider into the movable frame in the opposite direction of material conveying, so that the inclined side contacts the movable frame. The resulting force causes the limiting block to slide inward, compressing the spring between the limiting block and the slider, until the limiting block is completely inside the slider. Then, slide the slider further to move the limiting block to the corresponding limiting groove. The rebound force generated after the spring is compressed pushes the limiting block to move outward, so that the limiting block enters the limiting groove. Then, remove the force applied to the pressure roller and the slider. The rebound force applied to the limiting block after the spring is compressed cancels the external force acting on the pressure roller, thereby realizing the installation of the pressure roller, simplifying the installation steps and improving the efficiency of pressure roller installation. 2. When materials are being conveyed normally, the pressure roller comes into contact with the material. The force generated after the two come into contact will drive the slider to move in the opposite direction, so that the plane on the other side of the limiting block comes into contact with the limiting groove, restricting the slider from moving further. This ensures that the pressure roller flattens the material, eliminates thickness differences, avoids the occurrence of "irradiation dead angles", ensures uniform penetration of irradiation rays and consistent dosage, and improves the effect of irradiating materials. In addition, there is no need to manually flatten the material, further improving the effect and efficiency of flattening the material. 3. When the thickness of the material changes, the screw is rotated on the base frame. Since the screw is threadedly connected to the movable frame, the movable frame slides on the base frame, adjusting the distance between the pressure roller and the corresponding conveying roller. This adapts to materials of different thicknesses, flattens materials of different thicknesses, avoids the occurrence of "irradiation dead zones", ensures uniform penetration of irradiation rays and consistent dosage, and improves the effect of irradiating materials.

[0020] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0021] This utility model provides a material flattening device for a transport line, such as... Figures 1-3As shown, the system includes a base frame 2 mounted on both sides of the conveyor line 1. A movable frame 3 is slidably connected to the base frame 2. A screw 4, threadedly connected to the movable frame 3, is rotatably connected to the base frame 2. A slider 5 is slidably connected to the movable frame 3. A pressure roller 6 is positioned between the two sliders 5. When the thickness of the material changes, rotating the screw 4 on the base frame 2 causes the movable frame 3 to slide on the base frame 2 due to the threaded connection between the screw 4 and the movable frame 3. This adjusts the distance between the pressure roller 6 and the corresponding conveyor roller, thus accommodating materials of different thicknesses. To prevent the formation of "irradiation dead zones" in materials of varying thicknesses, ensuring uniform irradiation penetration and consistent dosage, and improving the effectiveness of irradiation, a limiting block 7 is slidably connected to the slider 5. A limiting groove 8 is provided on the movable frame 3. One side of the limiting block 7 has a flat surface 9 that contacts the limiting groove 8, and the other side of the limiting block 7 has an inclined surface 10 that contacts the movable frame 3. A spring 11 is provided between the limiting block 7 and the slider 5. The component force generated by the contact between the inclined surface 10 on one side of the limiting block 7 and the movable frame 3 causes the limiting block 7 to... The limiting block 7 slides inward, compressing the spring 11 between the limiting block 7 and the slider 5 until the limiting block 7 is fully inserted into the slider 5. Then, the slider 5 is moved further, causing the limiting block 7 to move to the corresponding limiting groove 8. The rebound force generated by the compression of the spring 11 pushes the limiting block 7 outward, causing the limiting block 7 to enter the limiting groove 8. Then, the force applied to the pressure roller 6 and the slider 5 is removed. The rebound force applied to the limiting block 7 by the compression of the spring 11 counteracts the external force acting on the pressure roller 6, thereby achieving the installation of the pressure roller 6. The installation process simplifies the steps of installing the pressure roller 6 and improves the efficiency of installing the pressure roller 6. In addition, the contact between the pressure roller 6 and the material generates a component force that drives the slider 5 to move in the opposite direction, so that the plane 9 on the other side of the limiting block 7 contacts the limiting groove 8, restricting the slider 5 from moving further. This ensures that the pressure roller 6 flattens the material, eliminates thickness differences, avoids the occurrence of "irradiation dead angles", ensures uniform penetration of irradiation rays and consistent dosage, and improves the effect of irradiating materials. Furthermore, there is no need for manual flattening of materials, further improving the effect and efficiency of flattening materials.

[0022] Preferred, such as Figure 1 and Figure 4 As shown, the end of the screw 4 is provided with a driven wheel 12, which has several radial grooves 13. A drive wheel 14 is rotatably connected to the base frame. Both the upper and lower sides of the drive wheel 14 are provided with levers 15 that contact the radial grooves 13. When the drive wheel 14 is rotated on the base frame 2, the levers 15 on the upper and lower sides of the drive wheel 14 contact the radial grooves 13. The resulting force drives the driven wheel 12 to rotate on the base frame 2, thereby transmitting torque to the screw 4 and causing the movable frame 3 to slide on the base frame 2. This allows the screw to adapt to materials of different thicknesses, flatten materials of different thicknesses, avoid the occurrence of "irradiation dead angles," ensure uniform penetration of irradiation rays and consistent dosage, and improve the effect of irradiating materials.

[0023] Preferred, such as Figure 1 and Figure 4 As shown, an arc-shaped groove 16 is provided between the two radial grooves 13. Arc-shaped blocks 17 that contact the arc-shaped groove 16 are provided on both the left and right sides of the drive wheel 14. After each adjustment of the position of the movable frame 3, the arc-shaped blocks 17 on both the left and right sides of the drive wheel 14 slide into the limiting groove 8. The resistance generated after the two contact restricts the driven wheel 12 from rotating on the base frame 2, thereby preventing the external force from unintentionally driving the driven wheel 12 to rotate, causing the movable frame 3 to rotate on the base frame 2. This ensures the stability of the overall structure, ensures that the material is evenly pushed flat, avoids the occurrence of "irradiation dead angles", ensures uniform penetration of irradiation rays and consistent dosage, and improves the effect of irradiating materials.

[0024] Preferred, such as Figure 1 As shown, a handle 18 is provided on one side of the drive wheel 14 to facilitate the rotation of the drive wheel 14.

[0025] Preferred, such as Figure 1 and Figure 2 As shown, the pressure rollers 6 are in multiple sets, which further improves the effect of uniformly flattening the material, avoids the occurrence of "irradiation dead angles", ensures uniform penetration of irradiation rays and consistent dosage, and improves the effect of irradiating materials.

[0026] Preferred, such as Figure 2 As shown, the base frame is provided with several vertical grooves 19, and the movable frame 3 is provided with guide blocks 20 that are slidably connected to the vertical grooves 19. After passing through the vertical grooves 19, the guide blocks 20 are provided with rollers 21 that roll in contact with the base frame 2, which drive and guide the movable frame 3 to slide on the base frame 2, ensuring that the multiple pressure rollers 6 and the corresponding conveying rollers are consistent, so that the material is evenly pushed flat, avoiding the occurrence of "irradiation dead angles", ensuring uniform penetration of irradiation rays and consistent dosage, and improving the effect of irradiating materials.

[0027] Preferred, such as Figure 2 As shown, a first bearing 22 is provided between the slider 5 and the pressure roller 6 to reduce the friction between the slider 5 and the pressure roller 6, improve the smoothness of the rotation of the pressure roller 6 on the movable frame 3, further improve the effect of uniformly flattening the material, avoid the occurrence of "irradiation dead angles", ensure uniform penetration of irradiation rays and consistent dosage, and improve the effect of irradiating materials.

[0028] Preferred, such as Figure 1 As shown, a second bearing 23 is provided between the screw 4 and the movable frame 3 to reduce the friction between the screw 4 and the movable frame 3, improve the smoothness of the screw 4 rotating on the base frame 2, and improve the efficiency of adjusting the position of the pressure roller 6.

[0029] Example 1 This utility model provides a material flattening device for a transport line, such as... Figures 1-3 As shown, when installing the pressure roller 6, fix both ends of the pressure roller 6 to the slider 5. Then, with the side with the inclined surface 10 facing the movable frame 3, slide the slider 5 into the movable frame 3 in the opposite direction of material conveying, so that the inclined surface 10 contacts the movable frame 3. The resulting component force causes the limiting block 7 to slide inward, compressing the spring 11 between the limiting block 7 and the slider 5 until the limiting block 7 is completely inside the slider 5. Then, slide the slider 5 further, so that the limiting block 7 moves to the corresponding limiting groove 8. The rebound force generated after the spring 11 is compressed pushes the limiting block 7 to move outward, so that the limiting block 7 enters the limiting groove 8. Then, remove the force applied to the pressure roller 6 and the slider 5. The rebound force applied to the limiting block 7 after the spring 11 is compressed cancels the external force acting on the pressure roller 6, thereby realizing the installation of the pressure roller 6, simplifying the steps of installing the pressure roller 6, and improving the efficiency of installing the pressure roller 6. When materials are being conveyed normally, the pressure roller 6 comes into contact with the material. The force generated after the two come into contact will drive the slider 5 to move in the opposite direction, so that the plane 9 on the other side of the limiting block 7 comes into contact with the limiting groove 8, restricting the slider 5 from moving further. This ensures that the pressure roller 6 flattens the material, eliminates thickness differences, avoids the occurrence of "irradiation dead angles", ensures uniform penetration of irradiation rays and consistent dosage, and improves the effect of irradiating materials. In addition, there is no need to manually flatten the material, further improving the effect and efficiency of flattening the material. In addition, when the thickness of the material changes, the screw 4 is rotated on the base frame 2. Since the screw 4 is threadedly connected to the movable frame 3, the movable frame 3 is driven to slide on the base frame 2, adjusting the distance between the pressure roller 6 and the corresponding conveying roller, thereby adapting to materials of different thicknesses, flattening materials of different thicknesses, avoiding the occurrence of "irradiation dead angles", ensuring uniform penetration of irradiation rays and consistent dosage, and improving the effect of irradiating materials.

[0030] Example 2 Based on Example 1, such as Figure 1 , Figure 2 , Figure 4 As shown, the handle 18 drives the drive wheel 14 to rotate on the base frame 2, so that the levers 15 on the upper and lower sides of the drive wheel 14 come into contact with the radial groove 13. The resulting force drives the driven wheel 12 to rotate on the base frame 2, thereby transmitting torque to the screw 4 and causing the movable frame 3 to slide on the base frame 2. This adapts to materials of different thicknesses, flattens materials of different thicknesses, avoids the occurrence of "irradiation dead angles", ensures uniform penetration of irradiation rays and consistent dosage, and improves the effect of irradiating materials. After each adjustment of the position of the movable frame 3, the arc-shaped blocks 17 on both sides of the drive wheel 14 slide into the limiting groove 8. The resistance generated by the contact between the two restricts the driven wheel 12 from rotating on the base frame 2, thereby preventing external forces from unintentionally driving the driven wheel 12 to rotate, causing the movable frame 3 to rotate on the base frame 2. This ensures the stability of the overall structure, ensures that the material is evenly leveled, avoids the occurrence of "irradiation dead angles", ensures uniform penetration of the irradiation rays and consistent dosage, and improves the effect of irradiating materials. In addition, the pressure rollers are in multiple sets to further improve the effect of uniformly flattening the material, avoid the occurrence of "irradiation dead corners", ensure uniform penetration of irradiation rays and consistent dosage, and improve the effect of irradiating materials. In addition, the base frame is provided with several vertical grooves 19, and the movable frame 3 is provided with guide blocks 20 that are slidably connected to the vertical grooves 19. After passing through the vertical grooves 19, the guide blocks 20 are provided with rollers 21 that roll in contact with the base frame 2. This serves to guide the movable frame 3 to slide on the base frame 2, ensuring that the multiple pressure rollers 6 and the corresponding conveying rollers are kept consistent, so that the material is evenly pushed flat, avoiding the occurrence of "irradiation dead angles", ensuring uniform penetration of irradiation rays and consistent dosage, and improving the effect of irradiating materials.
